Exhibit 4_RFI.pdf

Solicitation No. 12837120R0034

Rattlesnake Water System Decommissioning and Toilet Building Demolition

Questions:

1. Will any geotechnical testing be required? No testing required

2. Not able to open the attachment in beta.sam.gov: Rattlesnake Demolition_2020_EE_SOI.pdf

Solicitation has the Schedule of Items. - SOI document was removed

3. Camping - Will the contractor be allowed to camp on site? Yes you can camp at the site

4. Staging area - Where will we be able to stage equipment, tools, or salvage material?

The site will be closed so you can stage it there.

5. Salvaged materials -Aare there any other materials, other than solar panels, that will need to be salvaged for the owner? No other items need to be salvaged

6. What about planters in front of restrooms? Do these need to be removed?

Plan on removing it but we may opt not to remove it depending on the vault toilet installer.

7. Septic Tank locations - They appear to be in front of the buildings in the asphalt. Please confirm location(s). Septic tanks are in the asphalt in front of the building

8. Access lids - There appear to be three or four access lids on top of the existing tanks if the tanks are in front of the buildings in the asphalt. After the tanks are filled with a sand slurry, do you want to just leave the lids as they are? The solicitation/scope of work says to fill with sand. Are we to assume that this is a sand slurry? Additional access lids are for junction boxes to leach field. These can remain

9. Concrete at entrance - Dowell into AC? Please clarify as asphalt and concrete expand and contract differently. Could we get a clarification on how you to dowel into existing asphalt?

Could we suggest a T-top type asphalt patch back that would typically be used on a trench and a roadway? (MAG detail 200-A, E, or D) Greased dowel into each edge. We went this way because you already have concrete there. To bring hot asphalt out just for this didn’t seem practical.

10. Pulverization of asphalt to 12 in – Please clarify as typical pulverization is 6 or 8 inches. What do you want to do with the asphalt and pulverized base material? Do you want to have it removed, recompacted, or just left loose in place? 3 inches of asphalt and 9 inches of base/subgrade. The pulverized material can remain in place and can just be wheel compacted not rolled. We want it to reveg.

11. Group Area: We could not get to the group area during our site visit, so we are not familiar with the ramada, or the vault toilet. Are there any pictures available of this area? What type and size are said vault? Can the vault be abandoned in place? Pictures are in the SOW. The pavement you are pulverizing goes down to the group site.

12. Bee removal – Can the bees be destroyed or do they need to be destroyed. Plan on doing bee removal.

13. Water availability - Is construction water available on site? If it is how many gallons per minute, and what is the location of the water available? Plan on getting water commercially.

14. Will work areas be able to be closed and what kind of area would need to be barricaded? The overall question here, is what kind of traffic control (pedestrian, or vehicle) or fencing needs to be done in the construction areas? The gate will be closed at the entrance.

15. At the entrance, where the concrete patch needs to be done on the crack, do we need an encroachment permit from the state or county? Traffic control needs to be determined for this area. No.

16. What size casing and how deep is the well? See Attachment mailto:Lisa@kmkaz.com

Form 55-58 Instructions Well Abandonment Completion Report

Introduction These instructions are a guide to filling out Form DWR 55-58 (Rev. 06/2019), entitled “Well Abandonment Completion Report.” Please review the instructions prior to completing the form in black or blue ink. Forms may be obtained at any Arizona Department of Water Resources (ADWR) office and at ADWR’s web site, http://www.azwater.gov. For information about the form or these instructions, contact the Groundwater Permitting and Wells Section at (602) 771-8527. There is no fee for filing this form.

When Form DWR 55-58 Must be Filed A Well Abandonment Completion Report must be filed within 30 days after a well is abandoned. The report must be filed by the drilling contractor or single well licensee that abandoned the well. A report must be filed for the abandonment of any type of well, including groundwater production wells, monitor wells, exploration wells, geotechnical wells and cathodic protection wells.

Instructions for Filling out the Form

Well Registration Number Fill in the registration number of the well in the space in the upper right-hand corner of both pages of the form. This is the number ADWR assigned to the well when the well was registered or when an application to drill the well was filed.

Section 1 – Abandonment Authorization Fill in the name, DWR license number and telephone and fax numbers of the drilling firm that abandoned the well.

Section 2 – Registry Information

Well Owner Information Fill in the name, mailing address and telephone and fax numbers of the owner of the abandoned well. If the well owner is a corporation, governmental unit or other entity, provide the name of a contact person.

Location of Well Fill in the following information relating to the location of the well:

• The street address of the property where the well was located. For monitor wells or other wells associated with contaminant investigations or remedial projects, this will usually be the same as the facility address.

• The legal description of the abandoned well location.

The legal description is the township, range, section, and in decreasing order, the quarters of that section so that the well location falls in a 10-acre block somewhere in that section. This information may be obtained from the county tax assessor’s office.

• The county tax assessor’s parcel identification number for the land where the well was located.

This information can normally be taken from the original Notice of Intent to drill the well, and may also be obtained from the county tax assessor’s office. Federal or State land will not have a parcel identification number.

• The latitude and longitude (in degrees-minutes-seconds format) and land surface elevation at the abandoned well location, and the method used to determine these data. Use of a Global Positioning System (GPS) receiver or a conventional survey is the preferred method, although the data may also be obtained through estimation from a USGS quadrangle map. If a GPS unit is used, the unit should be adjusted to use the NAD-83 datum.

Please indicate if the geographic coordinate datum used was NAD-83, and if not, which datum was used.

Section 3 – Questions Check the appropriate boxes and fill in information indicating the following:

1. Whether any information exists indicating that water in the well has historically been contaminated, is currently contaminated, or may be contaminated. If yes, provide an explanation.

2. Whether there is any other name or identification number for the well.

3. Whether the well had a surface casing of at least 20 feet and grout in the annular space surrounding the casing for at least 20 feet prior to abandonment. If not, indicate whether the top 20 feet of casing was removed prior to setting the cement plug.

Form 55-58 Instructions (Rev. 06/2019) Page 1

Well Abandonment Completion Report

4. Whether the well was backfilled above the cement plug.

5. Whether the well casing was video logged.

6. The reason the well was abandoned.

Section 4 – Original Well Construction Design Section 4 contains three tables for filling in information on the original well construction design. ADWR recognizes that this information will not always be available, particularly for older irrigation, stockwater or domestic wells. It should be available for monitor and remediation wells, or more modern wells with good records. Fill in as much information as possible.

In the Existing Borehole table, fill in the diameter of the existing borehole in inches, and indicate the depth interval for each change in diameter. In the Existing Casing table, fill in the outer diameter of the casing in inches, check the appropriate boxes indicating the type of casing material and the type of perforations and fill in the slot size of any perforations. Fill in the depth interval for each change in information. Please note that not every interval will be perforated. Check the “Blank or None” box for non-perforated depth intervals. If the type of casing material or perforations is not listed, describe the type in the appropriate box. Finally, check the appropriate box indicating whether the existing casing is in good, fair or poor condition.

In the Existing Annular Material table, check the appropriate boxes indicating the type of annular material or filter pack installed at each depth interval. Fill in the size of the filter pack used. Provide the depth interval for each change in information. If the type of annular material is not listed, describe the material in the appropriate box.

Section 5 – Actual Well Abandonment Design Section 5 requires information on the actual well abandonment design. In the boxes in the upper right-hand corner, fill in the depth to water and the date when abandonment was completed. The two tables below that box require information on the casing treatment and the sealing or fill material.

In the Casing Treatment table, check the appropriate box indicating the type of casing treatment that was used. If the casing was removed, check the “casing removal” box and provide a description of the removal technique in “Remarks.” If the type of casing treatment that was used is not listed, explain the treatment in the appropriate box. If the casing was perforated during treatment, describe the size and frequency of perforations for each interval. The casing treatment must be indicated by depth interval, and the depth interval must be filled in.

In the Sealing or Fill Materials table, check the appropriate box indicating the sealing or fill material that was used. Note any changes by depth interval. Also, fill in the mixing ratio of the material and check the appropriate box indicating whether the ratio is by weight or volume. Finally, fill in the volume of material used for each depth interval.

Below the two tables, fill in information on the actual abandonment method and the emplacement method of sealing or fill material. The Department’s Well Abandonment Handbook must be consulted before filling in the actual abandonment method. The standard method and the five alternative methods are described in the handbook. Check only one abandonment method. If “Other” is checked, provide a description of the method in “Remarks.”

Signature Block The form must be signed and dated by the drilling firm’s qualified party. The name and title of the person signing the form must be typed or printed in the space above the signature.
